JOHN HERMAN, OF LOS ANGELES, CALIFORNIA.

VENEERING APPARATUS FOR BRICK AND BLOCK MACHINES.

Application filed September 27, 1915.

T all whom it may concern Be it known that I, JOHN HERMAN, a. citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Veneering Apparatus for Brick and Block Machines, of which the following is a specification.

This invention relates to brick and block making machinery, and has for its object to provide a means for producing a brick or block having a veneer finish, thereby permitting the brick or block body to be made of a relatively cheap material and the face to be made of a better material.

My invention relates particularly to a mold box construction into which coarse material is fed through a central tube and veneering or facing material through tubes disposed at the sides of the central tube. The facing material is cut off by a movable blade which forms one side of the mold box and presses the veneer against the body material. A portion of the material is then cut off in the mold box and delivered to any desired receiving means.

In the drawings accompanying this specification and forming a part thereof: Figure 1 is a side elevation of a construction embodying my invention in which two sides of a brick or block may be veneered. Fig. 2 is a plan view as seen on the line 2-2 of Fig. 1. Fig. 3 is a reduced section as seen on the line 3-3 of Fig. 2. Fig. 4 is a section taken on the line 4--4 of Fig. 3. Fig. 5 is an enlarged detail of a section taken on the line 55 of Fig. 1. Fig.6 is a reduced section similar to Fig. 3 showing the movable blade in'position when it has pressed the veneering or facing against the body of the brick or block. Fig. 7 is a perspective view of a brick or block illustrating the structure thereof.

More specifically, 8 indicates a tube for the body material which is fed therethrough.

10 is a tube for feeding facing material for one side of the brick or block, while 11 is a tube for feeding facing material for the end of the brick or block. A mold box 12 having fixed walls 17 and 18' on two sides is provided on the third side with a movable blade 14 forming a wall and on the fourth side with a movable blade 15 forming another wall. Tube 8 is adjustably secured. to wall 17 by screws 16 so that it may be ad Specification of Letters Patent.

justed vertically. A slidable bottom plate 13 for cutting off material is disposed at the lower end of the mold box. An upright post 19 preferably an extended part of wall 35 is secured to the wall 18 and a similar upright 20 is disposed opposite 19 adjacent the inner section of blades 14 and 15 providing a frame for supporting the guide bars 22 and 23 by which blade 14 is guided. Opposite to upright 20 is disposed an upright 21 forming with upright'2O a frame for supporting guide bars 24 and 25 by which is guided-a blade 15.

Bar 22 is pivotally secured to upright 19, the pivot connection being made by a pin at the upper end of the bar as indicated at 24 in Figs. 3 and 6. Oppositely disposed to guide bar 22 is a guide bar 23 of the same form and similarly pivotall'y supported at its upper end. A frame for supporting the blade 14 is provided and consists of guide blocks 26 and 27 which are rabbeted at the outer edge as indicated at 28 and 29 to receive the guide bars 22 and 23, and are connected by cross pieces 30, the guide blocks and cross pieces being preferably integral. Secured upon cross bar 30 and to the guide blocks 26 and 27 by means of screws or any other suitable securing means is the blade 14. Blade 14 overhangs the grooves 28 and 29 forming with the guide blocks 26 and 27 channels for receiving guide bars 22 and 23.

By reason of the construction just described, it will be obvious that the frame carrying blade 14 may be moved longitudinally, it being guided upon strips 22 and 23. This longitudinal movement upward results in opening the side of the mold box 12 and connecting it with the tube 10. The pivotal. connection of the guide bars 22 and 23 per-. mits transverse movement of the blade 14; this movement being effected in the operation of the machine when the blade 14 is in its lowermost position.

Guide block 26 is provided with an outstanding wing 31 having an elongated aperture and guide block v27 is similarly constructed with a wing 31 having an elongated aperture. In the elongated apertures in wings 31 and 31 is disposed a shaft 32, permitting slight transverse, movement of the shaft. The shaft 32 is mounted in vertically movable bars 33 and 34 which are disposed on the outstanding walls 35 and 36 formed by extensions of one leg of each of the uprights 19 and 20. An inclined wall 37 is disposed across walls 35 and 36 forming a chamber in which the end of feed tube 10 is disposed. Bars 33 and 34 are guided for true vertical movement by means of straps secured to thewalls 35 and 36 and are provided with laterally extending arms 38 and 39 which are disposed for engagement by rollers 40 and 41. Roller 40 is mounted upon an arm 42 affixed to a shaft 43 and roller 41 is mounted on arm 44 affixed to shaft 43. Shaft 43 is mounted in bearings A handle 1s shown secured upon the side walls 35 and 36. for rocking the shaft 43 thereto.

F iXedly secured to shaft 43 are arms 46 and 47 connected by a cross rod 48. Sliding in grooves in walls 35 and 36 and disposed adjacent to wall 37 is a movable plate 49 carrying at its lower edge wedges 50 and 51. Wedges 50 and 51 have inclined faces which engage with the blade 14. Pivotally secured to the upper end of plate 40 are links 52 and 53 provided with elongated slots in which cross rod 48 is disposed. The slotted links 52 and 53 and rod 48 provide a lost motion connection between arms 46 and 47 and plate 49 whereby the plate be moved downwardly only at the end of the rocking motion of shaft 43.

In order to maintain the slidableblade 14 normally in a position where the free end of the blade is in its outer position, bars 54 and 55'are slidably mounted upon the walls 35 and 36 and are pivotally secured to the bars 22 and 23 at their lower ends by means of pins 56, particularly shown in Fig. 5. A projecting portion 56 is provided at the end of the bar 54 and extends through slot 57 in the wall 36. A laterally extending lug 58 is provided on the bar 55 and is engaged by springs 59, thus tending to push the rod 57 outward and hold the blade 14 in its outer position as shown in Fig. 3. An ear 60 is mounted upon the wall 36 and is provided with a threaded aperture through which a threaded screw 61 passes. Screw 61 serves as an abutment for limiting the outward movement of the bar 55, and therefore the outward pivotal movement of blade 14. Bar 54, ear 62, screw 63 and spring 64 mounted on wall 35 are similar in construction and arrangement to bar 55, ear 60, screw 61, and spring 59.

In order to protect parts of the veneering mechanism from the material fed to the mold boX I have provided a plate which is disposed in grooves in the walls 35 and 36 and acts as a shield. A parallel plate 71 is mounted in grooves in the walls 35 and 36 to protect the slidable plate 14 and may be raised and lowered to conform with the dimensions of bricks and blocks of different depths.

The operation of the device will be understood from a description. of the operation of the veneering mechanism for one side of the brick or block.

The coarse material for the brick or block is fed through tube 8. The veneer facing material through tube 10. Assuming that the members of the device are in a position shown in Fig. 3, the coarse material passes downwardly resting upon the plate 13 which is in closed position. Facing material fiows downwardly through the tube 10 and rests against the side of the coarse material. Handle 45 is moved upward rocking shaft 43, swinging arms 42 and 44 and moving the shaft 32 downwardly. Thus forcing the framework and the blade 14 downwardly cutting off the facing material with the layer resting against the coarse material. Further movement .of the handle 45 moves the arms 46 and 47 downwardly and'rod 48 against the ends of the slots in the links 52 and 53, forcing plate 49 downwardly and carrying with it the wedges 50 and 51. As the wedges move into their lower position they force the blade 14 inwardly pressing the facing material against the body material. This position is indicated in Fig. 6.

'For the purpose of carrying the plate 14 downwardly in its movement, helical tension springs 72 and 73 are provided which connect the shaft 32 and arms 42 and 44. This construction permits continued movement of the plate 49 and wedges 50 and 51, after the blade 14 has reached its lowermost position, thus crowding blade. 14 forwardly toward the coarse material. In the upward movement of the arms 42 and 44 the blade 14 is carried upwardly by reason of rollers 40 and 41 engaging the arms 38 and 39. After the veneer has been placed upon the body and pressed against it, the mechanism is in the position shown in Fig. 6. The handle 45 is then moved to its lowermost blade 14. Movement of the handle 45 upwardly results in the cutting off of the facing material and compressing it forming stock for another brick or block.

hen handle 45 is moved to its lower.

position the blade 14 is raised and is held against the slice which has been cut off from the facing or veneering pulp. The wedges 50 and 51 holding the blade against the slice. In this upward movement blade 14 crowds or forces the slice of the facing or veneering material against the body and trowels it. When blade 14 is raised a predetermined height, it disengages wedges 50 and 51 and is then drawn back a predetermined distance by springs 59 and 64 which act upon bars 54 and 55. Guide plate 13 is now withdrawn and the material with the veneer or facing in place drops down into a receiving memher which has a bottom in it, for further pressure or treatment. After the pulp has been dropped guide plate 13 is closed and position, raising movement of handle 15 causes plates 14: and 49 and wedges 50 and 51 to repeat the operation.

. Operation of the handle 45 causes opera tion of the facing mechanism on two sides of the brick or block, as movement of shaft 13 causes movement of arm 65, gears 66 and 67, arm 68 and rock shaft 69 moving it in synchronism with rock shaft 43, thereby moving blade 15. After the handle 15 has been moved upwardly sliding gate 13 is withdrawn allowing the stock to move downwardly in the tube tothe floor of a receiving receptacle, then the plate 13 is replaced, cutting off the stock for a brick or block.

It is obvious that the device described can be made to operate automatically and supply stock to receptacles arranged upon a movable platform. It is also obvious that one or more faces may be veneered by this mechanism. A machine having movable walls on three sides would be most desirable in practice and it is within the scope of my invention to use any number of movable walls as desired. For the sake of clearness, I have herein shown my invention embodied in a machine having only two movable walls. If only one face is desired, the blades on the other sides will be let down and not raised, which can be done by disconnecting arm from shaft 13. If no veneer is desired operating handle 45 is brought to its uppermost position. Thus blades 11 and 15 will form two walls of the mold box and fixed walls 17 and 18 will form the third and fourth wall.
